Use when running a ClickHouse server for high-volume OLAP: choosing a MergeTree engine and ORDER BY/PARTITION BY keys, ingesting billions of event/log/metric rows, pre-aggregating with materialized views, or fixing a query that scans instead of pruning. NOT in-process file analytics (that is `duckdb`), NOT OLTP CRUD indexing (that is `postgresdb`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ClickHouse analytics ClickHouse is a multi-user, always-on, replicated columnar server built to ingest continuous high-volume writes and answer aggregation queries over billions of rows in milliseconds. You reach for it when the workload is "append a firehose of events/logs/metrics, then GROUP BY them for dashboards." Target **26.3 LTS** (v26.3.12.3, 2026-05-22) — several defaults below changed in the 26.x line, so version matters. The fork before you write any DDL: files on a laptop, in-process, no server, no concurrent writers → `../duckdb/SKILL.md`; app CRUD, point updates, foreign keys, row locks, RLS, migrations → `../postgresdb/SKILL.md`; `clickhouse-server`, replication, concurrent writers, 100M+ rows/s ingest → this skill. Instrumenting capture (GA4/PostHog) is `../analytics/SKILL.md`; charting the result for humans is `../dashboard/SKILL.md`; deciding which metrics matter is `../kpi-framework/SKILL.md`. ClickHouse is the engine underneath all three. ## Pick the engine first The engine decides dedup and merge behavior, and you cannot change `ORDER BY`/`PARTITION BY` later without a rebuild — so choose before typing `CREATE TABLE`. …

How to install
mdr add ericrisco/rsc-harness/clickhouse-analytics@sha256:f960bff9e55096c8The line at the top of this page pins the label git:20260729.3ecb845, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
